Love, if you will out and eat write you can. It's healthy abd maintainable. I lost 40 in three mouths. Completely healthy. Just makes sure you drunk tons of water and green teas. Eat right. And with out. You will lose the weight.
It is i done it before with alot of dedication, it's hard but if you do it the right way it possible.
That's 20 lbs in one month? Don't think it's healthy
